DEVICE FOR WINDING SPRINGS OF SHADE-ROLLERS.

Specification of Letters Patent.

Application filed. February 8, 1913.

Patented July 29, 1913.

Serial No. 747,036.

To all whom it may concern:

Be it lmown that I, LoUIs FERRY, a subject of the King of Italy, residing at Derby, in the county of New Haven and State of Connecticut, have invented a new and useful Improvement in Devices for Winding Springs of Shade-Rollers; and I do hereby declare the following, when taken in connection with the accompanying drawings and the characters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this application, and represent, in

Figure 1 a side view of a device for winding shade roller springs constructed in accordance with my invention. Fig. 2 a front view of the same. Fig. 3 a rear view. Fig. 4 a top or plan view. Fig. 5 a view in longitudinal section.

This invention relates to an improvement in device for winding springs of shade rollers, the object being to provide a simple device which may be attached to a shade roller either before or after the shade has been attached and by which the spring rod within the roller may be turned so as to wind the spring to the desired tension; and the invention consists in the construction hereinafter described and particularly recited in the claims.

In carrying out my invention, I employ a frame comprising two parallel bars 2, 3, with bearings 4 and 5 for a shaft 6 which may be locked against longitudinal movement by the introduction into one of the bearings, as for instance, 4:, of a locking key 7 which engages with a groove 8 formed in the shaft. The outer end of this shaft carries a ratchet wheel 9 and is provided with a crank handle 10. Secured to the casing adjacent to the ratchet wheel 9 is a spring pawl 11 which prevents the movement of the shaft in one direction, but leaves it free to turn in the opposite direction. Hinged to the outer ends of the bars 2 and 3 are jaws 11 and 12 the inner faces of which are slightly concaved adapting them to fit upon rollers of various sizes. Pivotally connected with one of the jaws is a yoke 13 which extends around the other jaw and carries a set screw 14 which may be turned against the jaw 11 so as to crowd the jaws upon a shade roller introduced between them. The inner end of the shaft 6 is formed with a notch 15 for the reception of the end of a spring rod 16 arranged within the shade roller 17, the end of this rod being usually flattened. A shade roller is introduced between the jaws 11 and 12 and the screw 14 turned to clamp the jaws firmly upon the shade roller whether the shade roller be provided with a shade or not. The hinged jaws will swing so as to centrally locate the roller in line with the shaft 6 and so that the end of the rod 16 may be engaged by the notch 15 of the shaft. VVhen thus in place the crank handle 10 is turned so as to wind the shaft 16 until the spring is given the desired tension. It will be understood that as it is turned the usual pawls employed in shade rollers will hold the stem against return movement which is furthermore held by the pawl 11 engaging with the ratchet wheel 9.

I thus provide at very low cost a device which may be readily carried about by any one hanging shade rollers so that if the springs are not wound to proper tension they may be readily wound before the shade is hung.

I claim 1. A device for winding shade roller springs comprising a frame having parallel sides, a rotary shaft mounted in said frame between said sides, said shaft formed in its inner end with a notch, jaws hinged to the inner ends of the sides of the said frame, and a yoke adapted to crowd the jaws together.

2. A device for winding shade roller springs comprising a frame having parallel sides, a rotatable shaft mounted in said frame between said sides, a crank handle applied to the outer end of the shaft, a ratchet wheel on said shaft, a pawl on the frame and adapted to engage with said ratchet, said shaft formed at its inner end with a notch, a pair of jaws hinged to the inner ends of the sides of the said frame the adjacent face specification in the presence of two subof the jaws cincavedf, alnd a yoke CFivotally scribing witnesses. connected wit one 0 tie jaws an passing around the other jaw, said yoke carrying a LOUIS FERRY 5 screw adapted to bear upon the other jaw Witnesses:

whereby the jawsmay be crowded together. FREDERIO C. EARLE, In testimony whereof, I have signed this CLARENCE FERRY.
